ABOUT
Commonly known as the pink silk tree, this plant is admired for its attractive and exotic appearance. It features a broad, umbrella-like canopy that provides dappled shade beneath. The leaves are fern-like, delicate and bipinnate, which means they're split into numerous leaflets, giving the foliage a feathery appearance. In the summer months, the pink silk tree is graced with fluffy, pink, brush-like flowers, which are composed of numerous thread-like stamens, giving them the appearance of silky tufts. These blooms have a light, pleasant fragrance and are known to attract a variety of pollinators, including bees and butterflies. The flowers gently cascade from the branches, contributing to the tree's graceful and whimsical look. The bark of the pink silk tree is smooth and has a light gray coloration, which can provide a stark contrast to the vibrant green of the leaves and the pink of the flowers. After flowering, the tree produces flat seed pods that hang in clusters, adding further interest to its appearance. This plant's alluring beauty makes it a favorite in ornamental gardens where a visual impact is desired.

Water
The Mimosa Tree, commonly known as the Silk Tree or Pink Silk Tree, should be watered deeply but infrequently to encourage deep rooting, which makes the tree more drought tolerant. Water the tree with approximately 1 to 1.5 gallons every two weeks during the growing season if there is no significant rainfall. During periods of extreme heat or drought, increase watering to once a week. In cooler weather or when established, the tree requires less water; reduce watering to once a month or even less frequently depending on the climate and soil moisture levels.
Light
The Mimosa Tree thrives in full sunlight exposure, meaning it requires at least 6 hours of direct, unfiltered sunlight each day. It is best suited for planting in a spot that receives full sun throughout the day, without shade from buildings or larger trees, as this will promote the healthiest growth and bloom production.
Temperature
The Mimosa Tree prefers warm conditions and can tolerate a range of temperatures, ideally thriving in temperatures between 70°F and 85°F. It can survive minimum temperatures down to around 10°F to 15°F, but prolonged exposure to temperatures below 20°F can be damaging to the tree. The optimal growing conditions are in USDA Hardiness Zones 6 through 9, where it can be planted outdoors year-round.
Pruning
Prune the Mimosa Tree to maintain its shape, remove dead or damaged branches, and to encourage healthy growth and flowering. The best time for pruning is in the late winter or early spring before new growth starts. Typically, once a year is sufficient for pruning, unless there are broken or dead branches throughout the year, which should be removed immediately to maintain the tree's health.
Cleaning
As needed
Soil
The Mimosa tree (Albizia julibrissin f. rosea) thrives in well-draining soil with a mixture of two parts loam, one part peat, and one part sand. This mix provides proper drainage and space for the roots to grow. The ideal pH for the soil is slightly acidic to neutral, ranging from 5.6 to 7.5.
Repotting
The Mimosa tree, being a fast grower, should be repotted every two to three years during its young stage to accommodate its growing root system. Once mature, repotting can be done less frequently and only as needed.
Humidity & Misting
The Mimosa tree prefers moderate to high humidity levels. While adaptable, it fares best with humidity levels above 50% to mimic its natural environment but is tolerant of lower levels.
Suitable locations
Indoor
Place in bright indirect light and ensure adequate space.
Outdoor
Needs full sun, space, and well-draining soil.
Hardiness zone
6-9 USDA
Life cycle
The Pink Silk Tree, or Albizia julibrissin f. rosea, begins its life cycle as a seed, which requires a period of scarification or stratification to break dormancy and germinate. After germination, the seedling grows rapidly, featuring compound leaves that are characteristic of the species. As the tree matures, it develops a spreading canopy and starts to bloom with fluffy, pink, filamentous flowers in early summer, which are attractive to pollinators such as bees and hummingbirds. Following pollination, the tree produces flat seed pods that mature in autumn and release seeds, continuing the cycle. Throughout its life, which can span several decades, the Pink Silk Tree experiences seasonal growth cycles with active growth in the spring and summer, and dormancy during the winter months in temperate climates. The tree reaches maturity and begins to reproduce sexually with flowering and seed production typically within a few years, marking its entry into the reproductive stage of its lifecycle.
Propogation
Propogation time
Late winter-early spring
Propogation: The most popular method of propagation for the Mimosa tree, scientifically known as Albizia julibrissin f. rosea, is through its seeds. To propagate the Mimosa tree effectively, one would collect its seeds in the fall after the pods have dried and opened. The collected seeds need to be scarified, which means slightly damaging the seed coat to encourage germination. This can be done by gently sanding the seeds or soaking them in hot water (about 190°F or near 88°C) letting the water cool before removing the seeds. After scarification, the seeds are typically sown in spring in well-draining soil and placed in a bright, warm location. A consistent misting to keep the soil moist is critical until germination, which usually takes several weeks. Once seedlings emerge and become sturdy enough, they can be transplanted to a more permanent location in the garden.
